create react-redux-with-selectors module

[guillaumearm]

apply new strategy development like this issue Tiqa/redux-polyglot#52

react-redux-with-selectors use redux-with-selectors as main dependency, so we need to work on a dev branch and follow this 3 principles :

• this branch must be as clean as master, so npm run prepublish must be ok.
• all master merges should be tagged by a new version. (on the master branch only)
• all change must be validated by react-redux-with-selectors unit testing before merge on master ( maybe find for an automation for doing this )

todo before close this issue :

• create a dev branch [DONE]
• explain this principles in redux-with-selectors CONTRIBUTING.md [DONE]
• pre-release react-redux-with-selectors 0.0.1 [DONE]
• write documentation for this [DONE]
